Ole Elsie has a leaky bladder and needs a new fuel tank. I am able to find a tank, but the question is 17 or 22 gallons? Are these interchangable as they look the same and the dimentions are the same (?? How can that be??).

Any assistance greatly appreciated.

They are interchangable, but use different straps. Let me know if you still do not have any luck, I think I still have a line on them but they are costly.
Also, I think Poltergeist (Rob) said autozone carries them too.

I just checked, autozone carries both of them, i think it was 240 for the 22 gallon and 220 for the 17.
